Title: Magnetic recording and reproducing device
Inventor: AMADA NOBUTAKA
IPC: H04N5/7826
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To record and reproduce a digital image signal to/from a common recording medium with a head constitution common to also conventional one while securing the compatibility with a conventional analog VTR. SOLUTION: At the time of recording/reproducing the digital image signal, a signal S.Ref made to be the reference for the speed and phase of a rotary drum is inputted through a changeover switch 415, meanwhile a changeover signal SW30Hz-A of the magnetic head for recording/reproducing the digital image signal is inputted through a changeover switch 427 respectively to a phase servo circuit 422. The phase difference between the reference signal S.Ref and the head changeover signal SW30Hz-A is detected in the phase servo circuit 422, and the detected phase difference signal is added with the speed difference signal from a speed servo circuit 421 by an adding circuit 423 and is returned to a drum motor through a motor driver. Thus, the rotary drum is phase- synchronized to the reference signal S.Ref.

Title: Gyrocompass
Inventor: SUZUKI MAKOTO
IPC: G01C19/38
Filed: 1985-07-24
Abstract: PURPOSE:To obtain a stable performance for a long time, by determing a followup gain to allow the maintaining of a followup performance not affected by characteristics of a saturated voltage. CONSTITUTION:The body of a gyrocompass is composed of a compass bowl and a liquid tank housing a liquid supporting it and a deviation angle generated by the relative movement of the compass bowl and the liquid tank is detected with a deviation angle detector section to output a deviation voltage to an amplifier section 18, which is made up of a gain deciding section 19, a conversion constant memory section 20 and a drive speed computing section 21. The deciding section 19 finely varies the liquid tank by a computation output based on the deviation voltage and a fine change in the deviation voltage within a non-saturation characteristic range of the deviation angle to determine the followup gain monitoring the current deviation angle. In the normal bearing measurement, the arithmetic section 21 computes the optimum driving speed of the liquid tank on the basis of the followup gain thus obtained and the conversion constant previously memorized in the memory 20. A liquid tank drive section receives the output of the amplifier section 18 and drives the liquid tank to obtain bearing signal. Thus, a stable control characteristic can be obtained.

IPC: G11B15/10
Filed: 1986-07-14
Abstract: PURPOSE:To surely transmit and disconnect power to each base and to miniaturize the overall mechanism by linking a movable gear to a reel drive motor through a power transmission part including a gear engaging with the movable gear. CONSTITUTION:As figure shows, a gear train transmits power from gears 221b  224   226  a friction gear 228   a gear 231   232  234   the movable gear 236, in that order. The gear 228 is so constituted as to superpose with gears 228a and 228b. If the rotational load of the gear 228b exceeds a set torque, the gear 228a develops a slip with respect to the gear 228b to regulate said torque below the set one. In such a way the gear 228 adjusts a higher torque, while the reel drive motor does a lower one. Accordingly power is surely transmitted and disconnected. Moreover a torque adjusting means is made unnecessary to miniaturize the mechanism.

Filed: 1981-10-16
Abstract: PURPOSE:To accurately detect the short distance to an obstacle through ultrasonic waves, by mounting a contact detector of prescribed length on a bumper or the like so that a predetermined length is indicated when the detector generates an output signal. CONSTITUTION:A signal of ultrasonic waves or the like from a transmitter 23 is reflected on an obstacle and detected by a receiver 24. A flip-flop 30 generates an output signal showing the time H from the reflection to the detection, so that a measuring unit 31 calculates the distance to the obstacle. The switch 13 of a contact detector provided on a bumper is located at the tip of the detector of prescribed length so that the switch puts a delaying circuit 42 in operation when the switch is brought into contact with the obstacle. As a result, a distance display unit indicates a predetermined length. A switch 16, which is turned on when the distance to the obstacle has become zero, acts not through the delaying circuit 42 so that the display unit indicates that the distance is zero.
